XPlaneCDU

XPlaneCDU is a remote control interface for the Control Display Unit (CDU) present in X-Plane 11. This app does not provide an FMS, but simply a way to control the existing CDU from an Android tablet or phone. Currently it works with the Zibo Boeing 737 and SSG 747 aircraft.
Requirements:
- X-Plane 11
- Download the ExtPlane v2 plugin from http://waynepiekarski.net/extplane and unzip it, copy the extracted directory into the Resources/Plugins directory
- Zibo's Boeing 738 or SSG's Boeing 748
- Open TCP port 51000 in Windows firewall for ExtPlane
- Multicast support on your network for auto-detection
XPlaneCDU will auto-detect your X-Plane instance assuming that multicast is working. Many routers do not support multicast properly, and so you can tap on the connection text or the CDU screen to configure a manual X-Plane hostname or IP address.
You must have the ExtPlane v2 plugin installed in your X-Plane 11 Resources/plugins directory. This plugin uses port 51000 to provide external control capabilities, so you must make sure that Windows firewall is not blocking it. You must download the binaries for the plugin from http://waynepiekarski.net/extplane - you cannot use the original ExtPlane v1 plugin because it has bugs related to string datarefs.
This application is open source, released under the GNU Public License version 3 (GPLv3) and available from https://github.com/waynepiekarski/XPlaneCDU - it is written in Kotlin and shows how to implement the complex screen layout on any device size. The plugin source code is https://github.com/waynepiekarski/ExtPlane and is forked from the original code at https://github.com/vranki/ExtPlane (licensed under GPLv3).
It should be possible to extend XPlaneCDU to work with other aircraft, but it must provide datarefs for the CDU text strings. The default X-Plane 737 does not support this, and every other payware aircraft uses non-standard datarefs. It should be possible to support the Flight Factor 757/767, but they already provide a web-based CDU.
I look forward to feedback on any problems. Visit the GitHub page to file bugs https://github.com/waynepiekarski/XPlaneCDU
Remember: extract the plugin from http://waynepiekarski.net/extplane into your Resources/plugins directory, and make sure port 51000 is not blocked by the Windows firewall.
